J AGKSON TAYLOR, OF NEYVBERRY, SOUTH CAROLINA.

SIDE-BAR SPRING.

$PECIFICATION forming part of Letters Patent No. 285,089, dated October 2, 1883.

Application filed July 26. 1853.

To all whom, it may concern.-

Be it known that I, JACKSON TAYLOR, of Newberry, in the county of Ncwberry and State of South Carolina, have invented certain new and useful Improvements in Side Bar Springs, of which the following is a full, clear, and exact description.

My invention consists of improvements in the construction of the springs; also in the means of connecting them to the side bars and to the body, and also in the means of staying the springs against lateral thrusts, whereby it is designed to provide more substantial. and better operating-springs than any new in use, all as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming part ot' this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 a side elevation of my improved spring. Fig. 2is a plan view of a clip-plate employed in the construction of the spring. Fig. Sis a plan view of the spring inverted, and a part of the brace by which the two Fig. 4 is a perspective view of an eccentric shackle-pin employed in connecting the springs to the side bars and to the body. Fig. 5is across-section of one of the side bars and side elevation of the shackle and clip by; which the spring is connected to the side bar. Fig. 6 is a front elevation of the shackle. Fig. 7 is a side eleration of a portion of a rocker and the clipplates employed for mounting the eccentric clip-pivot thereon, and Fig. 8 is a perspective view of one of said plates.

Myimprovement in. the spring consists of the bent intermediate plates, a, in combination with an upper curved plate, I), for connecting to the body or the rockers supporting the body, and with the lower curved plate, 0, for connecting with the side bars, said plates a being bent nearly double, as shown, and arranged with the bends near the longitudinal center of plates 1) and c, and the arms or branches extending along said plates therefrom toward the ends, and beari 11g on them to add their supporting power to them. Near the bends of plates a they are connected. to upper plate, I), by clips (I, the bolts of which pass (No model.)

through the clip-bars c, that are forged onto'a plate, 1'', that rests on the top of Z), to hold said clips firmly in place. Said plates a are also clipped to plate 0 by clips g, the bolts of which pass through clip-bars 1 that are formed on the ends of branches of a stay-brace, 7.1, that extends from one spring to the other for stay ing them against the lengthwise thrusts of the body, which would take cit'cct on the springs laterally. The plates 1) 0 will have a stud under clips (I and to enter indentations in the plates (1, for staying them against displacement, and near the ends of the branches of plates a they will be connected to plates 2) c by the usual. slot in one and nib in. the other. I make the plates 1) c wider in the middle than at the ends, and form an eye, I, in the end for fitting on a shackle-pin, m, having eccentric pivot-bearings a, by which it is pivoted in the shacklcframe 0, so that it will turn and compensate by its eccentric throw the variations in the lengthy of the springs in consequence of their expansion and contraction, and thus will prevent side thrusts on the side bars and rockers.

The dotted lines in Fig. 1 show by the curved line the lengthening of the spring under the load, and by the vertical line the compensating effect of the shackle-pin by turning on its eccentric pivots. 1n the case of the body resting on the ends oi. the upper part, b, of the spring, I arrange the sl'lackle-pins mwith their pivots at the lowest point in the normal position; but for the plates 0, suspended from the side bars, I arrange the pivots uppermost in the normal position, which gives the best results in the action of the eccentric shackle-pin. In order to mount these eccentric shackle-pins in their bearings, 11 use separate an gle-platcs 1], for the connection with the rockers s, and bolt said plates onto the rockers separately by bolts 1,- bnt the shackle to connect with the side bars, a, I make in two parts by separating the base-plate o, as shown in Figs. 5 and 6, and secure them together bythe clip-bolts 10, which 5 pass through both parts of said base-plate.

I do not abandon or dedicate to the public any patentable fcatu re herein set forth and not hereinafter claimed, but reserve the right to claim the same, either in a reissue of any pat:

IOO

cut that may be granted upon this application or-in other applications for Letters Patent that I may make.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The bent platesa, the upper ones'being slightly curved upward and the lower ones curved downward and upward, in combination with the upper curved plates, 1), and the lower 10 dently with the plates a and upwardly at their outer ends, said plates 12 and 0 having eyes Z,

shackles having'eceentrically-pivoted shacklepins, side bars, and rockers, substantially as and for the purpose set forth.

2. The bent plates to, in combination with upper and lower plates, 1) and c, and being connected by clips (1 and g, said clips (Z being secured to clip-bars a, connected to plate f, and 20 clips connected to clip-bars 17, formed on the curved plates, 0, both being curved coincibranches of the stay-brace k, substantially as described. 3. The combination, with a carriage-spring,

of shackles to connect the spring to the side pins pivoted eccentrically in said shackles, to compensate for the varying length of the springs, substantially as described.

4. The combination, with the carriagesprings, having eyes Z at their ends, of the 50 shackles, with their shackle-pins m fitting in the eyes-Z of "the springs, and having the eecentrically-projecting pivots n, supported or pivoted in apertures in the plates 0 of the shackles, substantially as and for the purpose 35 set forth.
